The purpose of this invention is to prolatter being substantially theentire length vide an improved construction of heater of the memberexcept as to the marginal adapted to utilize the gaseous products offlange, 22, which corresponds dimensionally combustion such as theexhaust from an to the marginal flange, 12, of the member,

The outlet pipe connection, 50, is

ever, has its cavity, 11, shorter than the registering apertures beingmade through cavity, 21, of the member, 20, that of the said web andpartition for connecting said no QII outlet. Both the inlet and theoutlet connections, 4:0 and 50, are secured at the apertures at whichthey are mounted by being originally diametered exteriorly for fittingaccurately in said apertures, and then crimped to grip the margin of theapertures at both sides as may be clearly understood from the drawings.It is entirely feasible, as mechanics familiar with this art willunderstand, to produce a perfectly fluidtight junction by thus crimpingthe pipe nipple, consisting of drawn tubing, upon the margin of theaperture in which it is thus fitted.

Each of the stampings, and is formed with longitudinally extendingcorrugations, 15, 15, in the lower member, 10, and 25, 25, in the uppermember, 20, said corrugations in each case stopping a little short ofthe pipe connections leading into and out of the stamping cavitiesrespectively, as seen at 15 and At the o;- posite end saidcorrugationssimilarly stop a little short of the location of the apertured CJI area,31, of the partition, 30. These corrugations are desirably of such depthas to make the flow path of the gases considerably restricted in crosssection as compared with the total cross sectional compass of thecavities of the said stampings beyond the length of the corrugations.This, it will be understood, is for two purposes, first, to increase theradiating area of the fixture, and second, to retard the flow of thegases to an extent which will afford opportunity for them to give uptheir heat. Preferably the aperturing in the partition, 30, throughwhich the gases pass from one side to the other of that partition is inthe form of a plurality of slots 31 as seen in Figure This is preferredfor the purpose of breaking up the gases and somewhat restricting theirThe inlet and outlet pipes, and 80, connected to the pipe connections,40 and 50, respectively, it will be understood, lead from and back tothe engine exhaust conduit, of whatever form, by which the exhaust gasesare led to the muffler or for final discharge. The present invention isnot concerned with the means for determining the flow of the exhaustgases to the heater or the contrary; and any suitable construction maybe employed for this purpose.

I claim 1. A heater for utilizing gaseous products of combustion,as theexhaust gases of an internal combustion engine,consisting of a pair ofstamped metal members each formed with a longitudinally extendingcavity, said members adapted to mutually close each other throughouttheir longitudinal extent in common when assembled with said cavitiesfacing each other, and a partition plate interposed between said membersand united fluid-tight thereto at the margins of their cavities, saidmembers having pipe connections leading into their respective cavitiesat opposite sides of said partition near the same end of the assembledstructure, the partition being apcrtured near its opposite end fordischarge of gases from one side of the partition to the other.

2. In the construction defined in claim 1 the mated stampings havinglongitudinally extended instruck corrugations of depth causing them toapproximate the partition, said corrugations in the two members as totheir longitudinal extent stopping short of the pipe connectionsrespectively.

3. In the construction defined in claim 1 one of said stamping membershaving it; cavity stopping short of the length of the cavity of theother member at one end, the web of the first mentioned member being ofthe full length necessary for lapping the entire length of the cavity ofsaid other member and having in its extent beyond said cavitythe openingfor pipe connection to the longer cavity of said other member.

4. In the constrinztion defined in claim 1, one of said stamping membershaving its cavity stopping short at one end of the length of the cavitat the other member, the pipe connection to said other member being madefor leading into its cavity at the part thereof which extends beyond thecavity of the first mentioned I member; whereby the connections to thetwo members may be at the same side of the assembled structure.

In testimony whereof I have hereunto set my hand at Chicago, Illinois,this 5th day of February, 1926.
